SPECIFICATION forming part of Letters Patent No. 485,496, dated November1, 1892. Application filed November 9,1891. Serial No. 411,344. (Nomodel.) i

T0 on whom it may concern:

Be it known that I, JOHN FRIAR, a citizen of the United States, residingat Hartford, in the county of Hartford and State of Connecticut,haveinvented certain new and useful Improvements in King-Bolts for Vehicles,of which the following is a full, clear, and exact specification.

The invention relates to the class of bolts which pivotally connect theoscillatory axle to the fixed running-gear or body of a wagon, carriage,buggy, phaeton, or similar wheeled vehicle; and the object is to providea simple and cheap bolt of this class, applicable to any vehicle, whichwill keep tighter, be less liable to break, and have less wear, andconsequently less rattle, than prior king-bolts.

To this end the invention resides in a connection so constructed thatthe holding-nuts set against a stationary part and themselves do notturn, while each of the moving parts is in contact with and held by asingle sta tionary part and does not pass through several pieces.

Referring to the accompanying drawings, Figure 1 is a front elevation ofa section of the forward portion of the running-gear of a carriage. Fig.2 is a plan of the same. Fig. 3 is an enlarged longitudinal verticalsection through the king-bolt and connected parts. Fig. 4. is a similartransverse section, and Fig. 5 is a detail longitudinal section of aheadblock of modified construction.

In the views, 1 indicates an axle formed of iron or steel of any desiredcross-sectional shape held to the usual wooden bed2 by clips 3, to whichthe lower half of the fifth-wheel 4: is secured in the customary manner.Held to the top of the head-block 5by a clip 6 are the springs 7, andsecured to the bottom of the block is the usual plate 8, from whichrearwardly project the reach-irons 9. The upper half of the fifth-wheelis held by bolts 10 to the block at the ends of the plate and by bolts11 to the reach-irons 9, to which is secured by bolts 13 the bridle-iron14. The axle and bed are also held together by the king-bolt clip 15 andits yoke 16. The circular shank of the king-bolt, which sets into acircular socket 17 in the lower face of the head-block plate, islongitudinally perforated forms the yoke for the spring-clip, is thick-'ened or provided with a hub 20, having a rectangular opening to receivethe rectangular part of the pivot to prevent the latter from rotating,as shown in Figs. 3 and 4, or this may be accomplished by securing aplate 21, havinga rectangular or oblong opening, to the top of thehead-block, as shown in Fig. 5.

When thepivot is passed through the kingbolt, plate, block, springs, andclip, it is held stationary and does not turn, so that the stationarynut may be tightly set against the top of the stationary spring-clip,drawing the king-bolt, which oscillates on the stationary pivot, asclosely as desired against the bottom of the plate.

The hub 21 of the yoke 16 for the king-bolt clip is also longitudinallyperforated with a circular opening, and in this opening fits a circularpivot 23, with an enlarged head, a rectangular portion that passesthrough a rectangular opening in the end of the bridleiron 14, and athreaded end to receive a nut 24. When this pivot is passed through theyoke and bridle-iron, it is held from rotation, and the nut, whichconsequently does not oscillate, is screwed as closely as desirableagainst the bottom of the stationary end of the bridle-iron. The upperend of the pivot 23 may be provided with a hub or stud 25 to projectinto a socket in the axle to prevent the parts from slipping out ofposition when together. WVhen the parts are connected together by themeans described, the king-bolt oscillates on the fixed pivot '18, withits upper end against the bottom face of the headblock plate, so thatthe nut 19 does not turn, nor is there any moving part which passesthrough the plate, block, spring, and clip, so as to unscrew the nut orwear the opening, causing rattling and exposing the pivot to the dangerof bending and breaking. At the lower end the yoke, which is secured tothe king-bolt, so as to be practically a part thereof, oscillates uponthe pivot 23, with its lower face against the face of the bridle-iron,so that the pivot does not turn in the bridle-iron to wear that openingand produce a cause of rattling, nor does the nut oscillate, so that itwill be unscrewed.

I claim as my invention- The combination, with the head-block 5, theaxle 1, and the bed 2, of clips 6 and 15, the latter of which isprovided with an apertured extension and the former with a bolt-hole atits upper end, a yoke 8, having a hub 20 with an angular aperture, and aseat 17 for the upper end of the extension of the clip 15, a pivot heldby its head in said extension and having a polygonal portion in theangular aperture of the yoke 8, and a screw-threaded end for a nut 19, ayoke 16, having a hub 21, nuts for screwing the yoke to the clip 15, abridle-iron 14, having an angular aperture, a headed pivot 23, held insaid yoke and pivoted with a polygonal portion to take into the angularaperture of the bridle-iron, and a nut 24 for the screw-threaded end ofsaid bolt, substantially as set forth.

JOHN FRIAR.
